Description

Die Erfindung betrifft ein Patienteninterface mit einem Kopplungselement für eine Bänderung. Für die Befestigung eines Patienteninterface (PI) an einem Patienten oder Benutzer wird meist eine Bänderung verwendet. Das PI weist daher Kopplungselemente für die Bänderung auf. Bei einem PI welches als Beatmungsmaske mit einer Stirnabstützung ausgebildet ist, befinden sich üblicherweise zwei Kopplungselemente an der Stirnabstützung und zwei Kopplungselemente an dem Maskenkörper. Die Verbindung von Kopplungselement und Bänderung kann unter Vermittlung von zusätzlichen Klips oder Adaptern erfolgen. Alternativ kann die Bänderung Schlaufen ausbilden, die unmittelbar an dem Kopplungselement befestigt werden. Die unterschiedlichen Verbindungen von Kopplungselement und Bänderung sind beispielsweise in der EP 2727620 A1 oder der US 20040045551 A1 beschrieben. Die bekannten Lösungen wiesen für ein gegebenes Bänderungsende immer nur ein definiertes Kopplungselement auf. Durch diese feste Zuordnung ist eine individuelle Anpassung für den Patienten meist nicht möglich.The invention relates to a patient interface with a coupling element for a harness. A harness is most commonly used to attach a patient interface (PI) to a patient or user. The PI therefore has coupling elements for the harness. In the case of a PI which is designed as a respiration mask with a forehead support, there are usually two coupling elements on the forehead support and two coupling elements on the mask body. The connection of the coupling element and the harness can be done by using additional clips or adapters. Alternatively, the harness can form loops that are attached directly to the coupling element. The different connections of the coupling element and harness are for example in the EP 2727620 A1 or the US20040045551A1 described. The known solutions always had only one defined coupling element for a given harness end. Due to this fixed assignment, an individual adjustment for the patient is usually not possible.

Die EP 2 818 196 A1 offenbart ein Patienteninterface mit einer Stirnstütze und einem Kopplungselement für eine Bänderung und vier Aufnahmemittel, die unterschiedliche Möglichkeiten der Ankopplung einer Bänderung bieten und somit zwei Ebenen bilden. Die EP 2 818 196 A1 weist einen federnden Verstellmechanismus auf, daher ist die Stirnstütze nicht einstückig aufgebaut. Zudem weist die Stirnstütze eine sehr geringe Neigung zu der Stirn eines Nutzers auf, weshalb eine Ebene, die an der Basis der Stirnstütze liegt, einen geringen Abstand zu den Ebenen der Aufnahmemittel aufweist. Diese aus vielen Teilen bestehende Stirnstütze ist nur aufwändig herstellbar, teuer und nicht leicht zu reinigen.The EP 2 818 196 A1 discloses a patient interface with a forehead support and a coupling element for a harness and four receiving means that offer different options for coupling a harness and thus form two levels. The EP 2 818 196 A1 has a resilient adjustment mechanism, so the forehead rest is not constructed in one piece. In addition, the forehead rest has a very slight inclination to the forehead of a user, which is why a plane that lies at the base of the forehead rest has a small distance to the planes of the receiving means. This forehead support, which consists of many parts, can only be produced with great effort, is expensive and not easy to clean.

Die EP 2 954 920 A1 offenbart ein Patienteninterface mit einer einstückigen Stirnstütze und einem Kopplungselement für eine Bänderung und Aufnahmemittel die eine Ebene bilden. Da die Stirnstütze keine Verstellfunktion aufweist ist die Neigung der Stirnstütze zu der Stirn eines Nutzers relativ groß. Eine Ebene, die an der Basis der Stirnstütze liegt, weist daher einen großen Abstand zu der Ebenen des Aufnahmemittels auf. Die Lösung der EP 2 954 920 A1 bietet eine nicht ausreichende individuelle Anpassung der Stirnstütze für den Patienten.The EP 2 954 920 A1 discloses a patient interface with a one-piece forehead support and a coupling element for a harness and receiving means that form a plane. Because the forehead rest has no adjustment function, the inclination of the forehead rest toward the forehead of a user is relatively large. A plane lying at the base of the forehead rest is therefore at a large distance from the plane of the receiving means. The solution of EP 2 954 920 A1 does not offer sufficient individual adjustment of the forehead support for the patient.

Es ist daher die Aufgabe der vorliegenden Erfindung ein Patienteninterface mit einem Kopplungselement für eine Bänderung anzugeben, dass eine individuelle Anpassung der Stirnstütze für den Patienten ermöglicht und zugleich für eine Vielzahl von Patienten anwendbar ist, ohne ein Stirnpolster und/oder einen Verstellmechanismus zu benötigen und trotzdem aus wenigen Teilen besteht, leicht und kostengünstig herstellbar ist und leicht zu reinigen ist.It is therefore the object of the present invention to provide a patient interface with a coupling element for a harness indicate that an individual adjustment of the forehead support for the patient allows and at the same time can be used for a large number of patients without requiring a forehead cushion and/or an adjustment mechanism and still consists of few parts, is easy and inexpensive to produce and is easy to clean.

Das Kopplungselement und das PI sind bevorzugt aus Polycarbonat, Polyethylen oder ähnlichen Kunststoffen im Spritzgussverfahren hergestellt.Thus, the coupling element 1, for example in the form of a tab, can be made of the same flexible material as the PI. As a result, it is preferred, for example, if the coupling element is designed in one piece with the PI or is coupled in two pieces to the main body of the PI via an interface. The coupling element and the PI are preferably made of polycarbonate, polyethylene or similar plastics in an injection molding process.

Das Kopplungselement kann ein Polster aufweisen, welches der Abstützung an der Haut eines Benutzers dient.The coupling element can have a cushion, which is used for support on the skin of a user.

Das Kopplungselement kann sich auch unmittelbar an der Haut eines Benutzers abstützen.The coupling element can also be supported directly on a user's skin.

Das Kopplungselement kann auch so gestaltet sein, dass ein Aufnahmemittel 5, 6 mit einem Bänderungsende 4 zumindest teilweise bedeckt ist und daher die Bänderung an der Haut eines Benutzers anliegt.The coupling element can also be designed in such a way that a receiving means 5, 6 is at least partially covered with a harness end 4 and the harness therefore rests against the skin of a user.

Das Kopplungselement kann einstückig als Teil einer Stirnabstützung ausgebildet sein.The coupling element can be designed in one piece as part of a forehead support.

The receiving means 6 is arranged closer to the plane E than the receiving means 5.

Ein Bänderungsende 4 kann alternativ an dem Aufnahmemittel 5 oder an dem Aufnahmemittel 6 auf einer Seite des Kopplungselementes befestigt werden. Da das Aufnahmemittel 5 näher zu der Symmetrieebene S angeordnet ist als das Aufnahmemittel 6, kann dadurch eine Feineinstellung der Länge des Bänderungsendes 4 erfolgen. Die Aufnahmemittel 5, 6 befinden sich zudem unterschiedlich weit von der Ebene E entfernt. Dadurch kann eine Feineinstellung des Verlaufes der Bänderung erfolgen.A strap end 4 can alternatively be attached to the receiving means 5 or to the receiving means 6 on one side of the coupling element. Since the receiving means 5 is arranged closer to the plane of symmetry S than the receiving means 6, the length of the harness end 4 can be fine-tuned as a result. The receiving means 5, 6 are also at different distances from the plane E. This allows fine adjustment of the course of the harness.
